Issue setting bootmode for imx95evk

[eramox]

I am working with an imx95 (board IMX95LPD5BB-19 REV A) and I have issues using bcu to change the boot mode of the board.

Note: other functionalities of bcu seems ok: monitoring, eeprom....

Important bit:

• whatever the boot_mode setted in the last commands, get_boot_mode always return the same value.

Investigation

BCU was reporting that it could not find the string corresponding to the hex values so I tried to change the mapping in the bcu source code with floowing patch:

diff --git a/board.c b/board.c

=> It did not fix the issue

Hi,
Thank you very much for your report!
Yes, this issue was found in the BCU test. I will fix this issue when I have time recently.

The main problem is that get_boot_mode is not working properly. Currently you can use the following command to reboot the board to the corresponding boot mode.
$ sudo ./bcu reset usb/sd/emmc -board=imx95evk19 -id=xxx

Thanks!
